What kind of remote should I research? - Industrial Robot

Hello! Thank you for checking this post out. I am a CS specialist who was assigned to a team of seven for a robotics project. Without giving away too many details we have to make a remote control car (the car being the size of a motorcycle). My quesiton is what kind of remotes should I look into?

What I have so far:

- I thought about using a Steam Deck and programming it to meet my requirements. The only thing I am concerned about is the range, as I want the range to be around 500 feet.

- DJI and similar drone controllers, they have incredible range but from what I understand they canot be programmed for anything except a DJI drone, and when I attempt to contact the companies it is a little difficult for me to understand what they are saying, and I am also confident that a customer service rep may not understand the kind of questions I am asking.

- ODIN 2. had some great qualities, progrmamable and everything I am like i said before concerned on the range of the controller because I think this is crucial for ensuirng project success

I also was tyring to look into companies such as RAVEN that produce large scale robotics and ask about their controllers but I havent had much luck contacting anyone. So if anyone here knows about any other companies that make remote controlled, large scale robots polease let me know,

I have also looked into communication methods liek XBEE and wifi (including antennas and range extenders) but like i mentioned I am a CS major and I am out of my wheelhouse, and the EE and ME team members are getting nowhere and I think they are to afraid to ask the internet.
